Appucatiun med may 11, 1910. serial No. 560,635.

To all whom it may concern: l

Be it known that I, FRANK Somer, a citizen of the United States,residing in Philadelphia, Pennsylvania, have invented certainImprovements in Padlocks, of which the following is a specification.

The object of my invention is to construct a combination adlock in sucha manner that the shacklewil be held at both the heel and the nose andthe combination mechanism will Vbe distributed the moment the lock isclosed. y

The invention relates also to ,certain details of construction whichwill be fully` described hereafter. y

In the accompanying drawings Figure 1,'is a perspective view of myimproved combination padlock; Fig. 2, is a view of ,the lock with therear casing removed, showing the shackle in the closed position; Fig. 3,is a view similar to Fig. 2,with the tumblers of the lock removed andthe shackle open; Fig.

4, is a sectional view on the line 4-4,'Fig, 2; Fig. 5, is a detachedperspective view of the shackle; Fig. 6, is a detached perspective viewshowing the series of tumblers and washers; Fig. 7 is a detachedperspective view of the cam plate; Fig. .8, is a perspective view of thedog; Fig. 9, is' a perspective view of thelocking bolt; Fig. 10, is aperspective view .of the device for throwing the dog out of engagementwith the tumblers; Fig'. 11, is a perspectiveview of the front plate;Fig'. 12, is .a perspective view of the handle; and Fig. 13, is a Viewillustrating `a modication of my invention.

A is the front casing of the lock and A is the rear casing, securedtogether by rivets or other fastenings B is the shacklemounted on apivot pin a secured to both sections of the case and this shackle has anose b engaged by the bolt C pivoted at c to the casing. The bolt ismade in the present instance from a plate; the engaging portion c beingturned at right angles lto the body portion, as shown in Fig. 9.

cured to a post a projecting from the casing,-

so that, while the tumblersare free to turn,

lthe washers are held in a fixed position.

The first tumbler has a pin g which passes through slots g inthe othertumblers and into one of the slots ein the disk E. A spring f is mounted-o'n the ivot pin al of the dog F and oneend of this spring restsagainst the nose of the d og and the other rests -againsta pin d on thecam plate D, tending to force the dog against the tumblers, The cam'plate D is recessed aty d2 for thepassage of a post a. v

Mounte on a post a2, secured to the casing of the lock, is a spring I,one arm z' of Which rests against the casing and the other .arm z" restsagainst a pin als on the cam plate D, and the spring returns the camplate to its normal position when the dog is released,

as shown in Fig. 2. The bolt has a projec- 'Patented Nov. 29, 19101`this cam plate its spring I Will returnA it to.

its normal position and will cause the bolt to belprojected into thenotch back of the nose of the shackle, as illustrated in Fig. 2. Thesurface s2 of the cam plate rests in front of the heel b of the shackleand locks the shackle in the closed osition, so that the shackle isdoubly locke namely, at the heel and at the nose.

When the cam plate is turned in the direction of the arrow, Fig. 3, todraw the bolt from the nose of the shackle, the edge s is moved out ofthe path of the heel of the shackle, so that the heel' is. released atthe same time as the nose, consequently, the spring k, mounted on thepivote, causes the shackle to spring open to the position shown in Fig.3.

`Mounted on the pin n projecting from the case and through the' openingd2 in the cam plate is an arm N which is shaped to pass and force thenose of the dog F ont of engagement with the tumblers as soon as the camplate is released. A spring n2 is attached yto this arm and bearsagainst the post a. `When the parts are inthe locked position the do 'ison one side of the point n of the arm and when the camplate is moved byoperating the handle E the dog moves past this point and the point actsas a cam to force the dog out of the notches in the tumblers,immediately releasing the plate, which springs back to its normalposition, as shown in Fi 2. This movement destroys the -combination.r

I preferably secure a. plate A2 on the face of the casin as Ishown inFigs. l and 11. This plate 2 has the flange a3 which incloses the innerportion a2 of the handle, which is notched to form a part of the clickmechanism. .Surrounding this ange are thecnunierals, in the presentinstance arranged as the dial of a clock, but it will be understood thatany number of numerals may be used, or letters, or other marks maybensed in place of the numerals. There are as many notches in thesurface e2 of the handle as there are numbers on the dial, and on thecasing are one or more projections with which these notched portions ofthe handle engage, so as to bring the handle in the proper position.

one of which may be discarded, if desired.

By the above construction it will be seen that l can make a combinationpadlock in which the combination is destroyed as soon as the shackle isclosed and locked, and that the shackle is held, not only at the nose,but

y also at the heel, making a very substantial,

and at the same time a comparatively cheap, combination lock.

vln lFig. 13, l have shown a modification of the invention in which thecam plate D', instead of being pivotally mounted, is mounted to slide inthe casing, so that when it is in its raised position it will hold thebolt C in the locked position and will engage the heel of the shackleB", and when depressed will force the bolt out of engage? ment with theshackle and draw away from the heel. A

rlhe dog F is in such position 'that on the rotary movement of thetumblers the plate will be drawn down through the medium of the dog andwhen the plate is raised the dog will be automatically thrown out by thepivoted. arm.
